Abstract: A theorem of existence and non-existence of solutions for a boundary value problem for the equations of axially symmetric gravitational field in vacuum is given using the method of functional solutions. The boundary value problem is reduced to a two-point problem for a Bernoulli equation. Conditions are given under which solutions exist or not exist.
